Commercials are one of the central reasons people tune into the Super Bowl. Companies spend millions of dollars on 30 second spots, knowing the most eyes imaginable will be on their commercials. To that end, corporations try to bring in high-end celebrities who could generate even more interest in their product or business. That's how pop sensation Justin Bieber wound up in a T-Mobile commercial during the game.

The commercial

The commercial actually made its debut several days ago, but it reached a large audience during a second quarter break in the Super Bowl.

The T-Mobile spot introduced Bieber as a "Celebration Expert" and displayed him critiquing different celebrations in the history of mankind. At the end, he told people to Tweet some of their best celebrations to him and he would share his favorite throughout the night.

Upon a cursory check it a little while later, it did appear Bieber was interacting with fans on Twitter during the Super Bowl and commenting on some of his favorite celebrations he had seen. Many responded to him with pictures of the man who used to star in the commercials for Six Flags, drawing a comparison as to what an aging Bieber may look like down the road.

Bieber and the media

Several years ago, Bieber stated that it was his dream to star in a Super Bowl commercial, an interesting request from someone who grew up north of the border.

He finally had his dream come true on Sunday and it quickly became the most buzzworthy commercial of the first half, mostly due to the pop sensation's presence.

The Super Bowl appearance came in stark contrast to the singer's latest interactions on social media. Bieber became frustrated with fans and their obsession to take pictures with him, so he stopped allowing fans to photograph him in public.

He also quit Instagram after negative interactions on the social media site. He has spent most of the past year touring in support of his album, "Purpose," so Sunday's commercial may spark a renewed interest he previously brushed off from fans and the media.
